Since the water pump is a necessary accessory, I am more okay with it running off the belt than a PS pump, but would try to find an underdrive pulley to cut the losses a bit, unless rerouting the belt is easy. 20% underdrive = 48% less power, in theory at least, and if that turns 3hp into 1.5hp or 5hp into 2.5hp at redline, I can stomach that.
The idea is alluring, and I am almost willing to throw money at the $459 system, but this is my DD and I need to complete service and some other mods that are incomplete this weekend so I can get back on the road next week. So this is not the responsible, practical path right now.

So, I am passing on the idea (for now and the foreseen future but not permanently).

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
